我刚刚创建了一个空的android项目,同时包含了该项目所需的依赖项,只有在添加com.google.firebasecom.google.android.gms时,我才会看到错误,它将在下面生成错误。


  /Users/macbookair/Desktop/ANDROID/APPTEST/app/src/main/AndroidManifest.xml:22:18-91
  错误:属性application @ appComponentFactory
  值=(android.support.v4.app.CoreComponentFactory)来自
  [com.android.support:support-compat:28.0.0]
  AndroidManifest.xml:22:18-91也位于
  [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86
  值=(androidx.core.app.CoreComponentFactory)。意见建议:添加
  'tools:replace =“ android:appComponentFactory”'元素
  在AndroidManifest.xml:5:5-21:19进行覆盖。


请任何人帮助我,我已经尝试了很长时间以解决此错误。

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.fexample.android.appz"
        minSdkVersion 18
        targetSdkVersion 28
        versionCode 2
        versionName "2.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {

        targetCompatibility JavaVersion.VERSION_1_8
    }
}

}
apply plugin: 'com.google.gms.google-services'

android { sourceSets { main { assets.srcDirs = ['src/main/assets', 'src/main/assets/public'] } } }


从下面的屏幕截图中,该implementation 'com.android.support:appcompat-v7:28.0.0'也有一个错误,但是当我成功构建apk时,我认为这不好。


  使用groupId com.android.support和androidx。*的依赖项不能
  被合并但被发现
  IdeMavenCoordinates {myGroupId ='com.android.support',
  myArtifactId ='support-fragment',myVersion = '28 .0.0',myPacking ='aar',
  myClassifier ='null'}和
  IdeMavenCoordinates {myGroupId ='androidx.swiperefreshlayout',
  myArtifactId ='swiperefreshlayout',myVersion ='1.0.0',myPacking ='aar',
  myClassifier ='null'}


java - 包含Firebase和GMS服务时,Android Gradle构建失败,发生异常-LMLPHP

最佳答案

我建议您尝试以下方法之一:

1)迁移整个项目以使用androidx库,您可以在菜单栏中的“重构”>“迁移到AndroidX”下进行操作。

2)将com.google.firebasecom.google.android.gms的版本从17.x.x降级到较低的版本
